The fruit processing line refers to the cleaning, lifting, sorting, crushing, peeling and pitting, beating and other pre-processing of the original fruit, to vacuum concentration, ultra-high temperature sterilization, aseptic filling to aseptic large bags of concentrated sauce or concentrated juice and other production lines of all or part of the equipment.The food sterilizing machine is a machine that takes food raw materials and processed products as the object. Through the sterilization and sterilization of microorganisms, the main factors that cause food deterioration, to stabilize food quality, effectively prolong the shelf life of food, and reduce the The number of harmful bacteria in food is surviving, and the ingestion of live bacteria can cause human (usually intestinal) infection or pre-produced bacterial toxins in food to cause human poisoning. The material is heated to 138-150°C through a casing heat exchanger in a continuous flow state, and is maintained at this temperature for a certain time (2-4 seconds) to achieve commercial sterility levels, and then in a sterile state. Filled in sterile packaging containers in a sterile environment. The entire sterilization process is completed in an instant at high temperature, which completely kills microorganisms and spores that can cause material spoilage and deterioration, and at the same time, greatly preserves the original flavor and nutrients of the food. This strict processing technology and precise processing method of equipment can effectively prevent the secondary pollution of food and greatly prolong the shelf life of the product. The UHT process preferably adopts the in-line casing heat exchanger sterilization system, because of its reliable working performance under high steam pressure and ultra-high temperature, especially the continuous working time can be as long as more than ten hours, thus achieving better performance than plate type heat exchangers.

A juice extracting machine, also known as a juice extractor, is a tool used to extract juice from fruits, herbs, leafy greens and other types of vegetables in a process called juicing. It crushes, grinds, and/or squeezes the juice out of the pulp. Some types of juicers can also function as a food processor. Most of the twin gear and horizontal masticating juicers have attachments for crushing herbs and spices, extruding pasta, noodles or bread sticks, making baby food and nut butter, grinding coffee, making nut milk, etc. Juice extracting machines are used for squeezing juice from citrus such as grapefruits, lemons, limes, and oranges. Juice is extracted by pressing or grinding a halved citrus along a juicer's ridged conical center and discarding the rind. Some reamers are stationary and require a user to press and turn the fruit, while others are electrical, automatically turning the ridged center when fruit is pressed upon.

An evaporating machine is a device used in a process to turn the liquid form of a chemical substance, such as water, into its gaseous form - vapor. In this process, the liquid is evaporated, or vaporized. The solution containing the desired product is fed into the evaporator and passes across a heat source. The applied heat converts the water in the solution into vapor. The vapor is removed from the rest of the solution and is condensed while the now-concentrated solution is either fed into a second evaporator or is removed. The evaporator, as a machine, generally consists of four sections. The heating section contains the heating medium, which can vary. Steam is fed into this section. The most common medium consists of parallel tubes but others have plates or coils typically made from copper or aluminium. The concentrating and separating section removes the vapor being produced from the solution. The condenser condenses the separated vapor, then the vacuum or pump provides pressure to increase circulation.

One example of an evaporator is a radiator coil used in a closed, compressor-driven circulation of a liquid coolant. This is called an air-conditioning system (A/C) or refrigeration system. It allows a compressed cooling chemical, such as R-22 (Freon) or R-410A, to evaporate/vaporize from liquid to gas within the system while absorbing heat from the enclosed cooled area in the process, for example a refrigerator or air conditioner. This works in the closed A/C or refrigeration system with a condenser radiator coil that exchanges the heat from the coolant, such as into the ambient environment. A different kind of evaporator can be used for heating and possibly boiling a product containing a liquid to cause the liquid to evaporate from the product. The appropriate process can be used to remove water or other liquids from liquid based mixtures. The process of evaporation is widely used to concentrate liquid foods, such as soup or make concentrated milk called "condensed milk" done by evaporating water from the milk. In the concentration process, the goal of evaporation is to vaporize most of the water from a solution which contains the desired product.

The traditional filling machinery mostly adopts mechanical control, such as cam distribution shaft, and then there are photoelectric control, pneumatic control and other control forms. However, with the increasing improvement of food processing technology and the increasing requirements for packaging parameters, the original control system has been difficult to meet the needs of development. New technology should be adopted to change the appearance of food packaging machinery. Today's food filling machine is a mechanical and electronic equipment integrating machine, electricity, gas, light and magnetism. In the design, we should focus on improving the automation of packaging machinery, combine the research and development of packaging machinery with computers, and realize mechatronics Control. The essence of Mechatronics is to organically combine machinery, electronics, information, detection and other related technologies from a system point of view and using the principle of process control to realize the overall optimization.

Generally speaking, it introduces microcomputer technology into packaging machinery, applies mechatronics technology, develops intelligent packaging technology, and combines it into a full-automatic packaging system for production according to the requirements of product automatic packaging process. The detection and control of production process and fault diagnosis and troubleshooting will realize comprehensive automation and realize high-speed, high-quality, low consumption and safe production. It can be used for accurate measurement, high-speed filling and automatic control of packaging process of aquatic processed food, which will greatly simplify the packaging mechanical structure and improve the quality of packaging products. For example, the most common plastic bag sealing machine, its sealing quality is related to packaging materials, heat sealing temperature and running speed. If the material (material and thickness) changes, the temperature and speed will also change, but the change is difficult to grasp. If microcomputer control is adopted, the best parameters of sealing temperature and speed of various packaging materials are matched and input into microcomputer memory, and then equipped with necessary sensors to form an automatic tracking system. In this way, no matter which process parameter changes, the best sealing quality can be guaranteed.

The food drying machine is suitable for industrial and mining enterprises, medical colleges and scientific research institutions to dry and heat items under vacuum. Its temperature controller adopts touch keys, digital LED display, PID intelligent control instrument, and PT100 platinum resistance temperature measurement sensor. Storage, heating, testing and drying are carried out in an environment without oxygen or full of inert gas, so food will not oxidize. The fruit washing machine is a machine for washing fruit. The machine has the functions of food purification, disinfection and sterilization and air purification. It can achieve 1. Food purification, disinfection and sterilization: degrade toxic substances such as pesticide residues in vegetables and fruits from the outside to the inside, and remove harmful substances such as antibiotics, chemical additives, hormones and heavy metal ions in meat and seafood; 2. Air purification: it can remove formaldehyde, paint smell and other harmful substances emitted from new decoration and new furniture; 3. Preservation of fruits and vegetables: washed fruits, vegetables, meat and other foods can extend the preservation period for 7 days and remove the peculiar smell in the refrigerator.
